Defense Department budget up 10%. Paid by other departments

Early word on the upcoming Trump federal budget is that Defense spending will increase by 10%, $54 billion. The money will come by cutting other departments. Supposedly Medicare and Social Security will not be touched. Taxes will be cut.

I find it quite odd that a military that has not won a war in 70+ years will have a budget increase. It's also interesting that Trump said,  “We spent $6 trillion in the Middle East, and we have potholes all over our highways and our roads.”  Where has the military been spending most of its money?
